I'm a beginner and thinking to buy Shure KSM141 mics to pair with the combo Mixpre-D>m10 (just ordered). I will be recording mostly folk and chamber music, unamplified. Maybe some nature and urban ambience. Not a long trips, 3 hours max, I think. And I've not sure about current draw of this mics, it's rated 4.65 mA at 48PH. It's not so high, but it's also not so low as 2 mA. So the question is how long will the MixPre-D (with 2 alkalines/lithiums on board) can supply the KSM141 pair, approximately? Doing a search on the taperssection, I've also noticed that this is not so popular mics on the board. But for me, it's very affordable choise because of cardioid/omni option built-in, PADs, low self-noise (14db) and finaly, price. But anyway, I have some hesitation about current draw of this mics. I will be very grateful if you can dispel my hesitation, or suggest some other mics under 1000$ with the low current consumption.
regards,
Vladislav
